Mycosis

A mycosis is an infection caused by fungus or yeast. Many factors can lead to vaginal mycosis or thrush: the pill, progestins, antibiotics, vaginal douches, synthetic underwear, tight trousers, etc.
If you get thrush, you should use a cleanser with an alkaline pH to reduce fungi, in addition to any medication prescribed by your doctor.

If symptoms persist, consult your doctor.
